ICE-BOX 0R REFRIGERATOR LINING.

Specification of Letters Eatent.

Patented Feb. 13, 31912..

Application filed. March 9, 1906. Serial No. 305,045.

To all whom it may concern:

Be it known that I, WILLIAM voN BAuM- EACH, a citizen of the UnitedStates, res1ding at Milwaukee, in the county of Mllwaukee and State ofl/Visconsin, have invented certain new and usefullmprovements in Ice-Box or Refrigerator Linings, of which the following is a specification,reference being had to the accompanying drawing, forming a part thereof.

The main objects of this invention are to produce independently of thecasin or housing, a strong durable ice box or re igerator lining whichwill not leak, which can be easily kept clean, and which will avoidwaste of ice, and generally to simplify and 1mprove the construction ofdevices of this class.

It consists in certain novel features of construction as hereinafterparticularly described and pointed out in the claim.

In the accompanying drawing like letters ate the same parts in bothfigures.

Figure 1 is a front elevation of an ice box or refrigerator liningconstructed in accordance with the invention; and Fig. 2 is a verticalsection of the same on the line 2 2, Fig. 1.

The lining a, which may be made of various forms and dimensions, isshown for the purpose of illustration as of rectangular form and havingfive closed sides. It is made in one piece of some suitable plasticmaterial. A composition consisting of the following ingredients in aboutthe following proportions is well adapted for the purpose: 100 poundsasbestos fiber, ounds wood fiber (sawdust), 100 pounds llquid magnesite.This composition, which makes a good nonconductor of heat, is capable ofbeing easily molded into the desired form and produces a tough durableand comparatively light monolithic structure impervious to air andmoisture. It is of a close homogeneous texture and molds with evensmooth surfaces which may be enameled or otherwise finished if desired.It will not break or crack easily, being sufliciently elastic and toughto resist the blows and strains to which ice box or refrigerator liningsare ordinarily subjected.

The internal corners of the lining are preferably coved or rounded asshown at b, to prevent fracture along the lines of the anglesand toavoid sharp corners or creases in which dirt will collect and which itis difficult to keep clean.

The lining isceptaole and shelf-supporting frame which may beconveniently constructed as shown, of galvanized iron pipe or metalrods. The upright members 0 of this frame are threaded at the ends andsecured in the upper and lower ends of the lining by nuts and washers d,bot-h inside and outside of the lining. The ends of the lining where theuprights c are secured therein, are preferably reinforced on the outsideby metal strips e, through perforations in which said members pass, thewashers of the outer nuts 'being. seated against said strips. Theuprights 0 are connected by cross members f, which rovided with an icere-' may be attached thereto as shown, by ordinary T fittings orcouplings g. These cross members support an ice receptacle (not shown)or a shelf h, on which such receptacle is. carried, while extra shelvessuch as h, for holding articles to be kept in the ice box orrefrigerator,'may be removably and adjustably mounted on said uprights.

The ice box or refrigerator will of course be provided on the open sidewith a suitable door which may be made of or lined with the samecompositlon or material of which the main lining itself is constructed.

The lining may be permanently built into a house or other structure, orfor a portable refrigerator, may be inclosed in a casing of wood, tile,metal or other suitable material, either with or without an interliningor filling of asbestos, sawdust or other material usually em loyed forthe purpose in the constructlon o refrigerators.

Various changes in the form and details of construction of the liningand the nature and proportions of the ingredients of the compositionentering into the construction of the lining may be made withoutdeparting from the principle and intended scope of the invention.

I claim:

- An ice box or refrigerator lining having its top and bottom, back, andtwo slde walls formed integral with each other to constitute percentageof wood fiber, substantially as a seamless lining without joints, havingthe internal corners alon the lines of the angles at the sides and bacfiof the lining curved, and consisting of a non-conducting,noncont-mctibleend non-expansible composition formed of substantiallyequal parts of asbestos and magnesite and materlally smaller described.10 In Witness whereof I hereto aflix my signature in presence of twowitnesses.
